摘要 用恒电流法研究了PbO_2—Ti/MnO_2电极上析氧反应动力学,得到了析氧反应动力学参数,反应历程及控制步骤;用分子轨道理论和量子化学计算分析了二氧化铅电极与二氧化锰电极的电催化性能,得到了与实验结果相一致的结论。 The kinetics of oxygen evolution reaction (OER) on PbO_2--Ti/ MnO_2 elec-trode has been studied using galvanistatic technique. In terms of kinetic parameters, the reac-tion path of OER is proposed. The electrocatalytic activity of lead dioxide and manganese dioxide has been discussed according to the theory of molecular orbit and quantum chemistry calculation. It is concluded that the electrocatalytic activity of manganese dioxide is higher than that of lead dioxid, which is in agreement with the experimental result.
